What two particles account for almost all of the mass of an atom?

Asked by pinkaylla

Answer (3)

The two particles that account for the mass of an atom are protons and neutrons. Electrons on the other hand are negligible mass, and so light they are considered without weight.

Answered by jserene01 | 2024-06-10

Protons and neutrons have an atomic mass unit (amu) weight of 1 while electrons are so light they are considered weightless.

The two particles that account for almost all of the mass of an atom are protons and neutrons. Protons are positively charged, while neutrons are neutral, and both are found in the nucleus of the atom. Electrons have minimal mass and do not significantly contribute to the overall mass of the atom.
